Bath, England, 1890. Mystery author Lady Amy Lovell receives an anonymous letter containing shocking news: her fiancé, Ronald St. Vincent, has been dabbling in something illegal, which causes her to promptly break their engagement. When Ronald dies in her library, however, Lady Amy has a more serious problem on her hands. Joining with fellow writer Lord Wethington, Lady Amy launches her first-ever investigation, and stirs up a hornet's nest of suspects, from the gardener who served time in prison for murder to a vengeful woman who had been spurned by Ronald.
